Earthquakes: a few, most at shallower depths and a few at deeper depths

Example: Himalayas The rock at a continental - continental convergent boundary is metamorphic because of all the heat and compression How are these connected? Stress type: Sheer stressFault type: Strike - slip

There is only ONE fault line!They are generally along divergent plate boundaries.

Example: San Andreas FaultWest coast of North America (excluding theJuan de Fuca Plate) Characteristics: -Formed from heat and pressure- Denser- Foliation - alignment of minerals- Coarsening of Crystals -Equigranular crystalline texture Involved in plate tectonicsBurial> not changing composition butminerology changes temperature must be 200 degrees C orhigher and the rock needs to have energy Shield Volcano Composite Volcano Cinder Cone VolcanoType 2 -Smallest of the three types-slopes are 30 - 40 degrees -mafic cinders-mostly formed in a year-Examples: Paricutin (1943)Sunset Crater Shield Volcano Type 1 -Largest of the three -Slopes are less than 15 degrees-They have mafic lava flows- Take over a million years to formExample: Mauna Loa Composite VolcanoType 3 -Most dangerous of the three.- Intermediate in size-Slopes are between 15 and 30 degrees-They have alternating layers of pyroclastics and felsic lava flows Hazards: -Lahars-Pyroclastic Flows-Ash Falls-Carbon Dioxide formed from crystallization of the silicate minerals

Most common type of rock

examples: basalt and granite How are these connected? The continental plate is made up of granite and the oceanice plate is made of basalt. Both of these rocks are igneous rocks! Formed from compactation and cementation

These are the most common types of rocks found on the surface.

There are two types of Sedimentary rocks: clastic and chemical How are these connected? Composite volcanoes are formed along this type of convergent plate boundary.
